From paola.giannetti@pi.infn.it Mon Sep 18 02:13:56 2006 Date: Wed, 02 Aug 2006 13:59:26 +0200 From: Paola Giannetti To: cardoso@fnal.gov Cc: Mauro Dell'Orso , Mauro Villa , Luciano Bosisio , Livio Lanceri , Dario Menasce Subject: informations about test team boards Hello, I am Paola Giannetti from INFN Pisa. I am part of the SLIM5 project that will need soon a test beam setup similar to the one used by BTEV. I know that Dario Menasce spoke with you about our future needs. I am in Fermilab now and I would like to meet you to understand if we can buy with your help each piece of the DAQ system you used on your Btev test beam (the old version that already worked and the italian group is using on their CMS test beam). If possible we would like to use your DAQ setup as it is now for Lab tests, to practice as soon as possible. We also need a modified version of these pieces for the future test beam, so we wonder if we can commit some work to Fermilab or to a company you already know since it worked on the old version. In the case it is possible we would like to have a rough estimate of the cost (we would ask a more precise quotation when the work is better defined). I attach a file with specific questions on all we need. I planned to stay up to August 14, but unfortunately I have to reduce the period and I am going back to Italy on August 7. Can we meet on August 3 or 4? Which time is the best for you? Thanks for any information you can provide us, best reagards Paola [ Part 2: "Attached Text" ] We would like to know for the set-up as it is: 1) price and availability of each piece of the old DAQ chain: hibrid module with pitch adapter, the board patching the connectors, the mezzanine, the PTA. Is there anything that can be borrowed, just to start practicing? 2) FPGA firmware source code: for the mezzanine and the PTA. Any description/manual of the code (if not on web). 3) Is it possible to access very specific board documentation/information? Schematics, layout, cad used to design each piece. Any documentation which might be usefull in addition to what is on web. (On web: descriptions, pdf schematics and layout) This would help a lot also to define the modifications we need to design new pieces for the test beam. Extension/developments: 4) To our knowlege the mezzanine has been tested connected with 2 hybrid modules only, but on the manual it is said that it can be connected up to 4 modules (on board there are 4 connectors usable). It will be important for us if we can connect 4 modules per mezzanine. [background: The test beam will have a telescope and a demonstrator. We plan to use a similar DAQ chain up to the mezzanine, but we plan to substitute the PTA with the EDRO, a new 9U VME board. In the latest SLIM set-up, we plan to have: 4 double side strip layers using 6 FSSR chip each - for the telescope 4 single side strip layers using 3 FSSR chip each - for the demonstrator 2 MAPS layers - for the demonstrator It is clear that at least in the demonstrator we need to read 4 different hybrid modules. If it is possible to have them connected to just one mezzanine we can plan to have an EDRO board with two mezzanines: one for the strips and the other for the MAPS. Otherwise we need at least three EDROs. We have to understand if the double side layers can be read out using just one hybrid. For design robustness, we prefer to consider that we need at least two hybrid modules for each double layer, for a total of 8 modules. If we can read 4 modules per mezzanine, the EDRO board devoted to the telescope will be equipped with 2 mezzanines, otherwise we have to consider to use 4 mezzanines. So we need to know the maximum PMC capability now, to understand how many mezzanines should go on the new EDRO board.] 5) Can Fermilab work on possible minor modifications of the boards they designed and if yes how do they evaluate the costs? [possible modifications: more powerfull FPGA for the mezzanine (if that constitutes the limit to read 4 modules, see question 4) or update of the firmware] 6) Can Fermilab work on possible major modifications of the boards they designed and if yes how do they evaluate the costs? [possible modifications: adapt the mezzanine to the MAPS read-out, which likely will mean at least a change in the firmware, if not more] 7) If Fermilab cannot work for the modifications, and if we are CAD compatible, can we have the projects to implement efficiently in Italy the modifications we need? 8) Can Fermilab help us to get in contact with companies that already developed some old pieces for possible changes? In particular for specific parts like the pitch adapters.
